msm8916-wcd codec is found in Qualcomm msm8916 and apq8016 processors. This codec IP is split in to two parts (Digital & Analog). Analog part is integrated in to PMIC PM8916 and the digital part is integrated into Application processor. Data transfer between Analog and Digital Die is done via a internal bus called PDM.
This patch adds support to Analog part of the Codec which is integrated into PMIC PM8916.
